From d7dd91ff236b90a8aca2d619554b07bcb82953c7 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 16 Oct 2007 01:29:52 -0700 Subject: [PATCH] ps3fb: default to 480p on DVI-D/HDMI if video=safe Default to the 480p video mode on DVI-D and HDMI displays if `video=safe' is passed on the kernel command line. This is intended to be used by `kboot'-style boot loaders (i.e. first-stage kernels) for the PS3, to provide a failsafe video mode. Signed-off-by: Geert Uytterhoeven Cc: "Antonino A.
